TPS25984B1RZJR

Overview

The TPS25984B1RZJR is a stackable integrated hot-swap controller and eFuse from Texas Instruments, designed for high-current power distribution. It operates within an input voltage range of 4.5V to 16V, with absolute maximum ratings of 20V DC and 23.5V transient. The device features a low on-resistance of 0.8mΩ and supports up to 70A current handling. It withstands negative voltages up to -1V at the output. Packaged in a 32-WQFN-FCRLF, it functions across a temperature range of -40°C to 125°C.

Feature Summary

• Stackable architecture enabling parallel connection of multiple devices for higher current capacity
• Accurate and fast current monitoring capabilities
• Robust protection against negative output voltages

Applications

• High-current power distribution systems
• Hot-swap server applications
• Industrial equipment requiring redundant power paths

Procurement Notes

Verify the specific suffix RZJR confirms the tape-and-reel packaging format and quantity. Ensure the B1 variant designation matches the required electrical characteristics. Confirm the WQFN package type aligns with PCB footprint requirements. Validate that the 4.5V to 16V operating range suits the system supply rails.

Selection Notes

Select this component when high current sharing via stacking is required. The 0.8mΩ resistance minimizes conduction losses. Verify compatibility with the system's hot-swap timing requirements. Ensure the 32-pin QFN package fits the available board space. Check if the accurate current monitor meets system protection thresholds.
